Default What PSU for 16 HDD Atom NAS

Hi,
I'm searching for a reliable PSU for an 16 HDD (3A spinnup current each)
and an Intel Atom 330 board with a 2,5" Notebook HDD for the OS.

Currently I'm using a Corsair TX 850W (CMPSU-850TX), in operation it takes around 120W in standby entire 30W! when booting it peeks at 1.xxA though my ampere meter isn't fast enough to record this reliable.

Staggered spinnup isn't an option cause I don't have backplanes that would keep pin 11 aflote (unless you know a source in Europe for cables with pin 11 floating that wont cost to much)

I'd like a power saving PSU with like 48-50A on the 12V rail (obviously a single rail design) that would be available in Austria, Europe.

PS: Can it case problems running a 850W PSU at only 150W or below (like 20 when the HDD's are off)?

Could you help me please
Owen Burnett

The Seasonic X650 and X750 are more power efficient than anything else available. The 650 has a single 54A 12V rail. The 750 has a single 62A 12V rail.

Yeah, the X650 has 88% efficiency at 63W and 90% at 135W, you can't beat that.
Not to mention the overall performance.

Aside from reduced efficiency, probably not.
